WAVE ivre-Ton.

Application :filed .Tune 8,

To all whom t may concern:

Be it known that I, CHARLES G. POLLEYS, a citizen ofthe United States, residing at West Somerville, vin the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements in Wave Motors, of which the following is a specification.

This invention'relates to wave motors and has for an object to provide improved means for employing the movement of'water under the act-ion of the wind or other causes producing waves, swells or the like.

A further object of the invention is to provide a buoyant float adapted to rise and fall with the rise and fall of the water and to convert such rising and falling motion into rotarymot-ion by newand improved means.

A further object of the invention is to couple with said conversion of the rise and fall the rotation ofthe float in opposite directions according to the incoming and outgoing wave motion and to convert said motion into rotary motion to add to the rotary motion produced by the rise and fall.

A further object of the invention is to provide a float of the general type of a scow or barge which shall rise and fall with the swell with meansl for converting the rising and falling motion ofthe barge into rotary motion to be added to the rotary motion produced bythe rise andfall of the float and the rotation of the iioat as hereinbefore mentioned.

Afurther object of the invention is to provide a new land yimproved type of pendulum weight within the buoyant rota-ting Afloat for moving the float downwardly with the receding of the buoyant eifectof the water.

With these and other objects in view, the

invention comprises certain novel elements, units, parts, combinations, mechanical movements,"interactions, connections and functions, as disclosed in the drawings'together with mechanical and functional equivalents thereof as will behereinafter more fully described and claimed.

In the drawings:

Figure 3 is a view in side elevation of the invention mounted upon .a ioating barge.

Figure 4 is a longitudinal diametrical secr tional View through the revolving float showing the pendulum weight therein.

Figure 5 is a detail sectional view of part of the gearing structure.

Like characters of reference indicate cor'l responding parts throughout the several views.

Theimproved wave motor which forms the subject matter of this application com prises a plurality of operative parts, one of which is a rotating float, indicated as an `entirety at A. This float A comprises a cylindrical drum or barrel 10 having tapered conical ends 11 with fins or paddles 12 spaced about its perimeter and extending im It is mounted for operative purposes upon 1'1" arms15 which said arms are fulcrumed to the supporting structure which in the type shown at Figures 1 and 2 is a stationary pier 16 and in the type shown at Figure 3 is a floating barge 17. This fulcruming is f'- preferably by way of a shaft 18 to which the arms 15 are rigidly attached so that the shaft- 18 oscillates with the rise andfall -of the barrel 10.`

To'convert this oscillating motionofthe shaft 18 into rotary motion, the shaft is provided with a gear 20 engaging a gear 21 (see Figure v2), rigidly mounted upon ya stub shaft 23. This shaft 23', carries a ratchethub 24 engaging a spring-pressed pawl25 cariried by agear wheel 26. This gear wheel 26' intergears with a gearl wheel 27. carried upon the shaft 28 through the medium of the idler 26. A second gear train-connects gear 2O and 27 there being a gearvwheel not shown meshing with gear 2()I which is mounted upon the stub shaft 31 which in turn is connectedby pawl and ratchet 30 to gear 29 in amanner similar to the `first gear traindescribed except for the omission of the idler 2G" so that, as the kbarrel VA falls, the motion is conf verted into a clockwise rotary motion 'of sha-ft 28by the gear29 and,' as citrises, it

is converted into similar motion of shaft 28 i' by the gear 26.

From the shaft 28 gearing to any source of use and ofvany type is employed. As here shown, a sprocket wheel 32 is Vcarried upon said shaft with a sprockety chain 33 running to a sproclret34- upon the shaft 35 which in turn carries a pulley*v 36 with'belt 37 running toa conventional motor 38.*It

is to be understood, however, thatV the invention is in no way limited to the train of gearing whether by sprocket or other-wellv known type of Vstepping up the rotaryvmotion from the shaft 28.Y A

To convert lthe reversely rotating motion of the barrel A into continuous rotary Vmotion, awspro'cket 39 is mountedupon thebar-Y rel A with a sprocket chain 40 running to a sprocket 41 upon a sleeve 42 rotating free ly upon the shaft 18. A second sprocket 43 is carried by the sleeve so that the sprocket chain 44 from said sleeve operates `the sprocket 45. In the type shown atF-igure 3,1 it is necessary to c arry this sprocket chain y barge 17 is anchored or secured by meansl i racks 51 is provided by rollers 52 carried 44 over idlersV 46, but it is obvious that the path of the chain will be determined bythe intervening f structure.y

The sprocketl 45 forms a part of-a motion" converting mechanism substantially identical to that hereinbefore described whereby continuous rotary motion is yimpartedto the shaft 47 carrying vthe 'sprocket 48 from which the chain 49 extends to a sprocket 50- carried also upon the shaft 35 so that the oscilf lating rotary motion of the barrel bythe inflow and outflow `of the wavesis converted into continuous: rotary motionV and added to the continuous rotary motion Hpro"- duced by the rise andfallof the barrel.

Irrespective of the type supporting structure, the barrel is provided with a pendulum weight` 50 swung upon the'shaft 13 within the barrel, clear of the barrel so that the latteris free to rotate unhamperedby the containedpendulum weight@` 7 I In the type of the device shown at Figure 3," an added motion is yconvertedin that of struts or racks 5l'V which maybe as convenience'dictates upon one or both sides of the barge. lMeans for accommodating the rise andpfall of the barge relative tothe motor is intended'to act with anyo'f the said water conditions, the rising and falling of the barrel being more especially intended for the choppy waves, the longer wavesacting more oftenyin rotating the barrel, whereas the swells will raise and lower the barge while actingV but little upon the rotating barrel. L The device, therefore, embodies mea-ns vfor obtaining power from' the movementof the water irrespective of whether the water has violent motion or only gently moving. 2

It is believed that from the foregoing de- Y scription of the constructionand interaction off-"several parts, the operation of the device under any condition of wave motion will be readilyfunderstood i What I claim-tok Vbe new and desire secureby Letters Patent is :v i
